[mapserver-users] More info on DNC problem

Derek, 

It sounds like MapServer can't find your proj4 library.  You can add a
line to the map file to tell MapServer where to look for proj.  Take a
look at:  http://mapserver.gis.umn.edu/docs/reference/mapfile/mapObj

If your first test is to just see if you can read the data, strip all of
the projection blocks out of your map file.  If you aren't trying to
re-project or serve the data us as a WMS, you don't need to specify the
projection.  Just make sure that your extent is expressed in the units
of the underlying projection.  (decimal degrees)

David.

	Hi 

	I used the command 

	ogrinfo -ro -summary
gltp:/vrf/c:/ms4w/apps/some_folder/data/DNC13/H1316030

	on a folder containing digital nautical charts to get the
listing below. I then created the map file using the info for layer 14 (
hydarea at hyd(*)_area (Polygon) ) and using the extents from orginfo with
hydarea at hyd(*)_area as its parameter. I tried testing the map file using
shp2img but keep getting the error "Projection library error. No such
file or directory" From what I can find from web searching etc, this
error description covers a lot of different errors.

	From what i can see from hydarea at hyd, hyd is a subfolder of
H1316030 i.e C:\ms4w\apps\some_folder\data\DNC13\H1316030\HYD and
hydarea is file inside that folder with the extension .AFT

	Can anyone offer any help

	Thanks
	Derek
